A UFC Lightweight title bout between the former champion Anthony Pettis and former top contender TJ Grant was targeted for this event. However, Grant revealed in mid-September that he has yet to be medically cleared after suffering a concussion in training and would not be eligible to compete on December 14 and opted to decline the bout. Pettis was then expected to face Josh Thomson in the event headliner. However, on November 10, 2013, it was announced that Pettis was injured and the bout was cancelled. The new main event was a rematch for the Flyweight title between Demetrious Johnson and Joseph Benavidez. Co-featured on the card was a bout between top bantamweight contenders Urijah Faber and Michael McDonald. Ian McCall was expected to face Scott Jorgensen at the event. However, McCall was forced out of the bout with an injury and replaced by John Dodson. Then on December 3, Dodson himself was forced from the bout after sustaining a knee injury. Jorgensen instead faced former Bellator Bantamweight ChampionZach Makovsky. Jamie Varner was expected to face Pat Healy at this event.

However, Moraga pulled out of the bout with an undisclosed injury and was replaced by promotional newcomer Alptekin Özkılıç. Carlos Condit was expected to face Matt Brown in a welterweight bout on the main card. However, on December 7, 2013, it was announced that Brown had to pull out of the bout due to herniated discs in his back. Sources close to the promotion on Saturday, December 7, 2013, told MMAjunkie no replacement was sought to meet Condit on the card, thus removing the fight entirely from the event.

Faber headlined or co-headlined each of the arena's previous four MMA events.
